The woom GO 3 gives kids their first real taste of riding without training wheels or a coaster brake
What Our Gearhead® Experts Are Saying:
"The GO 3 drops the coaster brake entirely, which is a bigger deal than it sounds. Kids in this age range who've already learned to balance can set off from a stop much more naturally, and it builds better braking habits earlier. Pair that with the quick-release seatpost and this bike genuinely fits the full 4 to 6 range."
woom built the GO 3 for kids aged 4 to 6 who are ready to ride confidently and independently, and the spec choices reflect that. There is no coaster brake — the freewheel setup lets kids pedal freely and set off from a stop without fighting the drivetrain, which is how better riders develop. At 13 pounds, it is light enough for a child this age to handle on their own and easy enough for a parent to carry when legs give out. The 95mm cranks match the longer legs of kids in this age range without overextending, and the quick-release seatpost clamp means saddle height adjustments take seconds as they grow through the 4 to 6 window. The steering limiter, oversized grip ends, and child-specific brake levers cover the safety details parents care about most.
Heads up - We do our best to keep bike specs and images current, but occasional component changes can happen without warning-and sometimes the photos might not show the exact build you'll receive. If you want to double-check the details, our Gearheads are always here to help.
